Description Zhang Cheng 2017-07-24 09:49:07 UTC 
Description of problem: Node status have been updated to "Unknown" in yaml, but didn't update in oc command line after stop node service.


Version-Release number of selected component (if applicable):
openshift v3.6.153


How reproducible:
Always


Steps to Reproduce:
1. Step up a cluster with at least one ready node:
# oc get node
NAME                                                STATUS                     AGE       VERSION
host-8-172-64.host.centralci.eng.rdu2.redhat.com    Ready,SchedulingDisabled   1h        v1.6.1+5115d708d7
host-8-174-67.host.centralci.eng.rdu2.redhat.com    Ready                   1h        v1.6.1+5115d708d7
host-8-175-183.host.centralci.eng.rdu2.redhat.com   Ready                      1h        v1.6.1+5115d708d7

2. Stop node service on host host-8-174-67.host.centralci.eng.rdu2.redhat.com
# systemctl stop atomic-openshift-node

3. Check node status for host host-8-174-67.host.centralci.eng.rdu2.redhat.com
# oc get node
# oc get node host-8-174-67.host.centralci.eng.rdu2.redhat.com -o yaml


Actual results: Node host-8-174-67.host.centralci.eng.rdu2.redhat.com status have been updated to "Unknown" in yaml, but didn't update in oc command line.
3. Check node status for host host-8-174-67.host.centralci.eng.rdu2.redhat.com
# oc get node
NAME                                                STATUS                     AGE       VERSION
host-8-172-64.host.centralci.eng.rdu2.redhat.com    Ready,SchedulingDisabled   1h        v1.6.1+5115d708d7
host-8-174-67.host.centralci.eng.rdu2.redhat.com    NotReady                   1h        v1.6.1+5115d708d7
host-8-175-183.host.centralci.eng.rdu2.redhat.com   Ready                      1h        v1.6.1+5115d708d7

# oc get node host-8-174-67.host.centralci.eng.rdu2.redhat.com -o yaml
... ...
  - lastHeartbeatTime: 2017-07-24T09:31:54Z
    lastTransitionTime: 2017-07-24T09:32:36Z
    message: Kubelet stopped posting node status.
    reason: NodeStatusUnknown
    status: Unknown
    type: Ready


Expected results: 
# Node host-8-174-67.host.centralci.eng.rdu2.redhat.com status should become "Unknown" both in yaml file and `oc get node`.


addition info: 
None.

Avesh - please take a look at what oc get printers for nodes are doing here.
Comment 2 Avesh Agarwal 2017-07-24 16:44:07 UTC 
sure, going to look into soon.
Comment 3 Jordan Liggitt 2017-07-24 16:49:42 UTC 
if the Ready condition is anything other than True, the summarizing printer outputs "NotReady"
Comment 4 Jordan Liggitt 2017-07-24 20:04:36 UTC 
I don't think this is a bug... the `oc get` output is intended to print "Ready" if the Ready condition is True, and NotReady otherwise.
